Donar

A Germanic god of thunder. Donar was also known as Thunor or Thonar to the Saxons and Thor to the Scandinavians. The Romans identified Donar with the Roman thunder-god, Jupiter.

Donar was the god of storms, thunder and lightning. His symbols were the axe or hammer, which was sometimes a symbol of fertility. The presence of the hammer also identified Donar with the Roman hero/god Hercules (Heracles), who wielded the club as a weapon. Donar or Thunor was much more popular among the rural population than Wodan (Odin).

In the Norse myths, Thor inherited Donar's attributes, and Thor became the strongest defender of the gods. Thor was the son of Odin (Woden) and Jord.

Thursday or "Thor's Day" was a sacred day of the week, which corresponded to the Roman dies Jovis or "Jove's Day", which was a sacred day for Jupiter. The modern Germans call Thursday, Donnerstag ("Donar's Day").
